crack jokes or make witty remarks
❍ 就是权门的清客，他也得会下几盘棋，写一笔字，画画儿，识古董，懂得些猜拳行令，～，这才能不失其为清客。(《鲁迅选集》Ⅳ—156) Even the proteges of officials had to be good at chess,calligraphy or painting,to have some knowledge of antiques,to be able to play drinking games,crack jokes or make witty remarks: only so did they qualify as proteges.
